The invention provides an airplane jack device. The airplane jack device comprises a front airplane jack and a main airplane jack; the structure of the airplane jack device is as follows: a two-stage actuator cylinder is mounted on an upper portion of a supporting structure; a leveler is arranged on a side surface of the two-stage actuator cylinder; a hydraulic control system is mounted on a side surface of the two-stage actuator cylinder to drive and control actions of the two-stage actuator cylinder; a foot and a rotating wheel are arranged on and connected to the bottom of the supporting structure. The airplane jack device is high in bearing capacity, high in height, fast, simple and convenient to operate, flexible to move, reliable in working, telescopic, and convenient to transport; as a result, the technical problems of relatively low height, inconvenience for folding and shrinkage and also inconvenience for transportation and storage of a jack in the prior art are solved.
